The field of vision is really small.
When you sweat, it really soaks the inside of the mask and makes it uncomfortable.
The ear coverings are awkward and chafe a bit

This mask just doesn't feel comfortable to me and it's hard to see out of it. It's one of those masks you feel like you want to take off all the time. That's not good. I have a large face though so maybe it's just me. On the bright side, it never fogs. Try before you buy
